钛是地壳可含量十分丰富的元素。按各种元素在地壳中所占重量的百分数大小排列,钛占第九位。土壤中含有丰富的钛。因土类不同,其含量变化有一个很大的幅度范围(100—1000ppm)。但由于它通常与硅酸盐结合在一起,不能被植物利用。土壤中有效态的钛往往在1ppm 以下。植物体含钛量约在1ppm 左右。钛化合物的农用研究在美国,日本、苏联、匈牙利等国均有开展,以匈牙利研究较多。I.Pais 等利用钛的抗坏血酸螯合物使小麦、辣椒等作物的产量得到提高。我国幅员辽阔,土类繁多,因此钛在农业上的应用具有广阔前途。自1984年起,我们与有色金属总院协作,开展了钛在农业上应用的试验研究。本文报道用~(32)P 和~(86)Rb 示踪方法研究钛对作物吸收~(32)P,~(86)Rb 的影响,并对钛的增产机理作了初步探讨。
Titanium is a very rich element in the crust. According to the weight of various elements in the crust as a percentage of the size of the array, titanium accounted for the ninth. The soil is rich in titanium. Due to different types of soil, the content of a wide range of changes (100-1000ppm). But because it is usually combined with silicate, it can not be used by plants. The available titanium in the soil is often below 1 ppm. Plant titanium content of about 1ppm. Agricultural research on titanium compounds in the United States, Japan, the Soviet Union, Hungary and other countries have carried out to study more Hungarian. I. Pais and other use of titanium ascorbic acid chelate so that wheat, peppers and other crops yield increased. Our country has a vast territory and a great variety of soils, so the application of titanium in agriculture has a bright future. Since 1984, we have collaborated with the Nonferrous Metals Institute to conduct pilot studies on the agricultural application of titanium. In this paper, the effects of titanium on ~ (32) P and ~ (86) Rb uptake by crops were studied by ~ (32) P and ~ (86) Rb tracing methods, and the mechanism of titanium production was discussed.
